A spark plug - El Dorado Chevrolet in McKinney, Texas

Car engines come to life thanks to the help of spark plugs. As the ignition source for the combustion process of your car’s engine, spark plugs are directly linked to your vehicle’s engine performance. If you are experiencing vehicle acceleration problems or poor fuel economy, then your spark plugs might need to be replaced.

Here is everything you need to know about spark plugs and when to replace them.

What Are Spark Plugs?

Spark plugs are connected to your engine cylinders and provide a spark of electricity that ignites the combustion so you can start your car. By creating the spark that combusts the fuel and pushes the engine’s piston downward, spark plugs are necessary to start the engine and keep it running.

When Should You Replace Your Spark Plugs?

There are some signs you can look out for to know when your spark plugs may be worn out and need replacing. Keep your ears open for some rattling, pinging, or knocking sounds when you start your engine, as that may indicate the pistons are not working properly. If you notice your car is having trouble starting, that can also be a sign your spark plugs aren’t working correctly. Another symptom of a worn spark plug is reduced vehicle performance and poor fuel economy. If you notice any of these problems, you should bring your car into El Dorado Chevrolet to get it inspected.

What Happens When You Replace Your Spark Plugs?

When you replace a spark plug, you can start your car with confidence knowing there won’t be a problem with your engine. New spark plugs also improve your vehicle’s performance by contributing to a fully functioning combustion system. Spark plug replacements are also better for the environment since you can maximize your fuel economy and reduce air pollution with less harmful emissions.
